This transform is still a part of Products.PortalTransforms for converting Word documents (doc, not docx). The documentation for this project http://wvware.sourceforge.net/ says that it is deprecated in favor of abiword. As far as I can tell Plone doesn't have another transform for this at least as part of core, has anyone used abiword? Or something else for the old type doc files?
I noticed that demo.plone.org simply doesn't have that transform, but our sites still have a lot of these files from users that it would be nice to index. We've used wvware on our older operating system environments, but since it is ancient and deprecated I have to have a good reason to need to install it again on our newer ones.
